308 clamp bangle wheel 610, so that bangle wheel 610 and load limiter seat 302 form a whole.By pulling 620 turns of chain
Start sprocket wheel 610, rotate bangle wheel 610 and be equal to and rotate load limiter seat 302, strength is passed through the first friction plate by load limiter seat 302
310 pass to ratchet assembly 311, so as to compress brake seat 312,200 turns of major axis is driven by the internal spline of brake seat 312
Dynamic, major axis 200 drives lifting main body 500 again, so that by heavy lift.
Reference picture 6, Fig. 7, Fig. 8, limit for tonnage component 300 can be rotated freely around major axis 200, while by sprocket wheel case 100
It is also to use rotatable connected mode between lifting main body 500, when in use, can be arbitrarily adjusted by pulling chain 620
Whole limit for tonnage component 300, the anglec of rotation of sprocket wheel case 100, can be achieved to tilt, transverse direction and the weights of all angles such as hang upside down and carry
Rise.
Reference picture 8, when hanging upside down, directly by the suspension of the hook of lifting main body 500 aloft, limit for tonnage component 300 and
Sprocket wheel case 100 rotates 180 °, it is necessary to which the goods of lifting is suspended on fixed hook, and pulling pulls chain 620, goods with it is whole
The control section of chain block rises or falls together, so, according to goods the height often lifted can be needed to be pulled to design
The length of chain 620.
The chain that guiding mechanism 700 includes being arranged on sprocket wheel case 100 imports and exports 710, and is arranged at chain turnover
Chain guide pad 720 on mouth 710, it is the strip holes set along sprocket wheel case 100 that chain, which imports and exports 710, and chain imports and exports 710
Along the place horizontal layout of bangle wheel 610, specifically, it is open side edge 711, chain guide pad 720 that chain, which imports and exports 710 both sides,
Both sides are provided with the chute 721 that slip is engaged with open side edge 711, and chain guide pad 720 is stuck in chain by chute 721
Between the open side edge 711 for importing and exporting 710 both sides, so as to be slided along the track at open side edge 711.Chain is oriented to
The guide through hole 724 of the guiding of opponent's zip strip 620 is provided with the middle of block 720, the chain 620 that pulls for being wrapped in bangle wheel 610 is worn
The guide through hole 724 for crossing chain guide pad 720 is drawn outside sprocket wheel case 100.Pull traction of the chain 620 using lifting field
Chain, the cross section of guide through hole 724 is can be by " ten " font of dragging chain so that dragging chain can only be according to guide through hole 724
Middle path implementation lifting.
The installation of reference picture 4, Fig. 5, for convenience chain guide pad 720, the chain guide pad 720 between chute 721
A pair of U-lags 723 along the arranged in tracks of chute 721 are provided with, the outside of two U-lags 723 forms the cunning for setting chute 721 respectively
Cell wall 722.By setting U-lag 723 so that setting the runner wall 722 of chute 721 has certain elasticity, is installing chain
During guide pad 720, chain guide pad 720 rapidly can be caught in chain and imported and exported in 710, chute 721 is caught in open side edges
Between edge 711, the installation of chain guide pad 720 is completed.
Using chain block when, can multi-angle pull pull chain 620, pull chain 620 by chain guide pad 720
Effect, pull chain 620 and bangle wheel 610 remain at same plane, occur without relative skew, then avoid stuck feelings
The appearance of condition.Because chain imports and exports 710 arc ports for being a strip, when pulling the lifting of chain 620, chain guide pad 720
It can be slided according to the angle of inclination for pulling chain 620 along open side edge 711, reduce the abrasion for pulling chain 620, so that
Increase pulls the service life of chain 620.
Reference picture 9, Figure 10, Figure 11, described lifting main body 500 also include the He of chain hoist wheel 510 being placed on major axis 200
A pair of fixations bonded to each other and be guide chain plate 540,540 ＇ of symmetrical structure, chain hoist wheel 510 is arranged on guide chain plate 540,540 ＇
Between.The rotating central hole 541 for accommodating chain hoist wheel 510, guide chain plate 540,540 ＇ patch are set in the middle of guide chain plate 540,540 ＇
Conjunction face is provided with chain guide groove 542, and chain guide groove 542 includes chain entrance 542a, the chain interlude being sequentially connected
